Photos: 14 Colorado counties' (mostly lousy) ozone pollution grades from worst to best
The American Lung Association's massive State of the Air report for 2014 is out, with the organization grading places all over the country in terms of air pollution, including Colorado.
Ozone-pollution figures for fourteen Colorado counties were available, and the ALA's judgments are harsh: Eight of the counties get grades of "D" or "F," with only two earning an "A." We ranked the photo-illustrated results, using data in other categories as tiebreakers and giving extra credit for providing data even if the scores are iffy. Count them down below.
Number 9: Jefferson County
Number 8: Weld County
Number 7 (tie): Douglas County
Number 6 (tie): Denver County
Number 6 (tie): Boulder County
Number 5 (tie): El Paso County
Number 5 (tie): La Plata County
Number 3 (tie): Gunnison County
Number 3 (tie): Garfield County
Number 1: Mesa County
Here's the complete State of the Air 2014 report.
